Heatwave: when the heat hits construction sites

On rooftops, in concrete courtyards or at the foot of scaffolding, working conditions quickly become grueling.

For construction companies, the question is no longer whether these episodes will recur, but how to continue working while protecting employees. Today, a construction company manager almost has to become a meteorologist. Schedules, team organization, daily tasks: everything is being rethought in light of the heat.

On the ground, companies are now adapting their construction sites to the rhythm of the heat waves:

• Teams start in the early hours of the day;
• more frequent breaks;
• reorganization of tasks to limit direct exposure to the sun;
• Indoor work is preferred when possible;
• Fresh water distribution and cooling equipment.

As in many sectors that work mainly outdoors, the risks are very real: dehydration, illness, loss of alertness, etc.

Added to this is another, often less visible, difficulty: the economic impact on businesses. The intense heat slows down production, complicates certain technical tasks, and can cause construction delays. For SMEs and tradespeople already facing a challenging economic climate, these weather events become a real issue of organization and economic survival.

Since 2025, however, construction companies can benefit, under certain conditions, from the bad weather unemployment scheme in the event of a work stoppage linked to the heatwave: extreme heat has become a weather event in its own right.

According to David Maciejewski, Vice-President of FFB Grand Paris Ile-de-France and President of CIBTP Ile-de-France: "Faced with the extreme heat, the priority for construction companies is clear: to protect employees while adapting the organization of worksites. Prevention, information and anticipation are essential to continue working safely."
